Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, a low-voltage draw-out type switch cabinet with safety protection performance, including the cabinet body 1, the inboard fixedly connected with a plurality of carrier block 2 of the cabinet body 1, sliding connection has a loading board 3 between two carrier blocks 2 of same height, holding tank 4 has been seted up at the top of carrier block 2, the bottom of loading board 3 is rotated and is connected with and removes wheel 5, it is located the inside of holding tank 4 to remove wheel 5, the top of carrier block 2 is equipped with ejection mechanism 6, concretely, ejection mechanism 6 can make to remove wheel 5 and leave holding tank 4 and conveniently rotate, the both sides of the cabinet body 1 all are equipped with a plurality of deployment mechanism 7, concretely, deployment mechanism 7 makes the circuit of loading board 3 top separated.

The scheme has the following working processes:

when equipment in the switch cabinet needs to be taken down, the unfolding mechanism 7 needs to be opened firstly, so that a circuit above the bearing plate 3 is separated from the bearing plate 3, then the circuit is combed, then the moving wheel 5 is ejected out of the accommodating groove 4 through the ejection mechanism 6, then one end of the bearing plate 3 is lifted upwards, so that the bottom of the bearing plate 3 is separated from the bearing block 2, then the circuit between the bearing plate 3 and the bearing block 2 is cleaned, the bearing plate 3 is pulled outwards, so that the equipment is taken out of the cabinet body 1, the equipment is overhauled or replaced, then the bearing plate 3 is put on the bearing block 2 again, the bearing plate 3 is pushed to enable the moving wheel 5 to slide into the accommodating groove 4, the position of the bearing plate 3 is limited, the unfolding mechanism 7 and the ejection mechanism 6 are closed, and the equipment returns to the original position.

According to the working process, the following steps are carried out:

when the equipment needs to be pulled out from the cabinet body 1, the circuit on the bearing plate 3 can be separated from the bearing plate 3 by the unfolding mechanism 7 and the ejection mechanism 6, so that the circuit cannot be pulled to cause other equipment to be damaged when the bearing plate 3 is pulled out, and the safety of the cabinet body 1 during equipment replacement can be ensured.

Further, ejection mechanism 6 is including wearing to locate the knock-out pin 601 of holding tank 4 bottom, spout 602 has been seted up to the bottom of carrier block 2, the inside sliding connection of spout 602 has squeeze bar 603, the one end of squeeze bar 603 is triangle-shaped, the bottom of knock-out pin 601 is rotated and is connected with gyro wheel 604, it is specific, when needing to use the ejecting holding tank 4 of moving wheel 5, need promote the inside squeeze bar 603 of spout 602, make the slope of squeeze bar 603 extrude to gyro wheel 604, gyro wheel 604 makes knock-out pin 601 rise when rotating on the slope, thereby will move the ejecting holding tank 4 of moving wheel 5, later stimulate loading board 3 a little, make moving wheel 5 leave holding tank 4 top, do not always promote squeeze bar 603.

Further, the deployment mechanism 7 is including offering in the adjustment groove 701 on cabinet 1 surface, a plurality of expansion pole 702 wears to be equipped with to the side of adjustment groove 701, the inside sliding connection of adjustment groove 701 has adjustment pole 703, the fixed surface of adjustment pole 703 is connected with a plurality of and is trapezoidal expansion piece 704, it laminates with adjacent expansion pole 702 to expand piece 704, concretely, when needs use deployment mechanism 7, can stimulate adjustment pole 703, the inclined plane that will expand piece 704 after the outside pulling of adjustment pole 703 and the contact of expansion pole 702, make expansion pole 702 rise, the rising of expansion pole 702 can be taken the circuit on the loading board 3 up, make the circuit can not be accurate with the contact of loading board 3.

Furthermore, a plurality of lifting grooves 705 are formed in one side of the adjusting groove 701, the unfolding rod 702 penetrates through the two adjacent lifting grooves 705, the unfolding rod 702 is elastically connected with the lifting grooves 705 through a compression spring 706, concretely, the lifting grooves 705 can limit the lifting position of the unfolding rod 702, meanwhile, the unfolding rod 702 can be in contact with the bearing plate 3 after the equipment is placed into the cabinet body 1 through the compression spring 706, and the situation that the line is pressed on the bearing plate 3 due to sloshing cannot occur.

Further, two limiting plates 707 are fixedly connected to the surface of the unfolding rod 702, the limiting plates 707 are attached to the inside of the adjusting groove 701, specifically, the limiting plates 707 can prevent the dislocation of the unfolding rod 702 when moving up and down, and the two limiting plates 707 can vertically move up after the unfolding rod 702 receives upward force.

Further, one side fixedly connected with of loading board 3 is the pull-out rod 8 of U-shaped, and is concrete, when needs exert force pulling loading board 3 to loading board 3, can exert force to loading board 3 through pull-out rod 8 is convenient.

In summary, when the equipment needs to be replaced or maintained, the equipment can be pulled out of the cabinet body 1 through the bearing plate 3, and in the pulling-out process, the circuit on the bearing plate 3 can be separated from the bearing plate 3 by using the unfolding mechanism 7 and the ejection mechanism 6, so that the pulling-out and pushing-in of the bearing plate 3 can not be interfered, and the situation that the circuit is damaged due to the fact that the bearing plate 3 drives the circuit is prevented.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
